Abstract (en)
[origin: US2006093847A1] A composite structure having improved ballistic toughness and suitable for use in a fan containment case is provided. The composite structure includes a plurality of core layers, a plurality of inner plies position between adjacent ones of the core layers, each of the inner plies being formed from an organic matrix composite, an inner skin located adjacent an innermost one of the core layers, and an outer skin located adjacent an outermost one of the core layers. In a preferred embodiment, the core layers are formed from a honeycomb material made from aluminum or an aluminum alloy.
